Life expectancy of the asphalt roof system: 20-40 years. The material will be the main factor when it comes to establishing a basis for the life expectancy of your roof. Although there are different grades of quality for each material, some materials are more durable than others. For example, asphalt shingles will never be able to compete against something like slate in a storm with strong winds and falling debris.
Life expectancy is one of the most important attributes homeowners use to decide what roofing materials to use when building or re-roofing a home. The right type of ventilation is as important as a quality subfloor when it comes to the durability and overall lifespan of your roof. The main component of asphalt tiles is oil, but they are hardened with cement fibers and durable mineral fibers, contributing to the life cycle of the roof. There is also the possibility of a large tree falling to the roof or other damage due to debris or accidents, which will naturally shorten the lifespan of a roof, regardless of the materials used.
As with other materials in an average home, such as siding, windows and foundations, there are several influences that affect the life cycle of the roof. Due to the variety of selections, there is no truly established answer for the average lifespan of a roof. When you choose a roofing company or contractor to replace your roof or install one in a new home, understand that choosing several types of shingles, shingles, metal, or any other roofing material is just one aspect of manufacturing a roof with a long lifespan. You'll also want to understand the average lifespan of the type of roof you're buying or installing in your specific geographic area and your unique weather patterns.
Major weather events, such as hurricanes, tornadoes, or other storms, shorten the lifespan of any type of roof, so even if the roof and house appear to be relatively intact after such an event, know that you should check the roof immediately to ensure that there are no minor problems that could become a major problem in the future. The lifespan of a 30-year roof can be 30 years or 3 decades, or it can last much shorter if a disaster occurs such as a fire, a large hailstorm, a tornado or a hurricane. The lifespan of a shingle roof depends largely on the type of shingle roofing material you choose and the regional climate factors that may apply. In reality, nothing compares to the look of a cedar roof, but the lifespan of the cedar roof depends on how the product is manufactured and how it is installed.
However, the actual lifespan of your roof depends on several things, including the type of roofing materials used and the environment. Slate roofs have one of the longest life expectancies of all roofing materials, ranging from 75 to 200 years. Since the average cost of a roof is thousands of dollars, you need to make sure it's done correctly. However, as the life expectancy of a roofing material increases, so does the price usually, which must be taken into account, at least for most people.
